LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 595,416, dated December 14, 1897.

' Application filed April 24, 1897. Serial No. 633,671. (No model.)

To aZZ whom it may concern.-

Be it known that I, JAMES C. SERGESON, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Shuttles, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a loom-shuttle which is provided with novel means for ad justing the tension of the thread or yarn in its passage therethrough, as will be hereinafter described, and pointed out in the claims that follow the specification.

Figure 1 represents a face View of a portion of a shuttle embodying my invention. Fig. 2 represents a side elevation thereof. Fig. 3 represents a section thereof on line a: m, Fig. 1. Fig. 4 represents a section on line y y, Fig. 1. Fig. 5 represents a section on line a ,2, Fig. 1. Fig. 6 represents another top view of the invention.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates the body of theshuttle, the same, excepting the feature of my invention applied thereto, being of usual construction.

B designates a passage in the body, near the front nose thereof, the same being adapted for the passage of the thread on the spindle. Adjacent to said passage Bis a sleeve 0, which is parallel therewith and has a throat D in the side thereof, the same communicating with said passage B. The base of said sleeve is open and communicates with the eye E, through which the thread is discharged, said eye extending transversely to said sleeve, both eye and sleeve occupying suitable openings in the body A, it being noticed that the passage B, the throat D, and eye E are in communication, so that the thread may be run therethrough. The opening in which the eye E is located communicates with the opening in which the sleeve 0 is located below the latter, which is seated on a shouldered portion of the walls of said sleeve-opening, so as to be flush with the Wall of the lower portion thereof. In order to hold the sleeve in position, I employ the screw F, which enters the body A and has its head adapted to rest upon and tighten against the adjacent edge of the sleeve, it beingnoticed that said edge is cut away,'as at G, so that the head of the screw may be below or within the surface of the body A.

H designates a pin which is driven into the body A and has a portion exposed and in contact with the edge of the wall of the passage B at the side toward the eye E, forming a bushing, so that the thread in its movement through said passage runs on said pin, which, being of metal or other hard material, is more durable than the adjacent portion of the body, which is wood, thus preventing the thread from cutting the Wall of said passage B. The

top wall of the sleeve is inclined or spiral indownward direction from the shoulder G to the throat or opening D, so as to direct the thread or yarn to said throat when primarily contacting with said wall and drawn outwardly in threading the shuttle through said sleeve and the eye E, it being noticed that the inlet end of said throat is considerably below the upper face of the body of the shuttle.

the thread thus being increased, the extent of.

the tension being adjusted by the degree of rotation of the sleeve. When the adj ustment is accomplished, the screw is rotated, so as to have its head press against the sleeve, thus holding and controlling the latter, as is evident.

The cut-away portion G of the sleeve 0 forms shoulders G G2 on the top of said sleeve, the shoulder G, owing to its adaptability to be engaged by the head of the screw F, preventing improper rotation in backward direction of the sleeve 0, while the shoulder Gr limits the forward rotation of said sleeve to an extent beyond which the throat D is no longer serviceable.

The upper and inner portions of the wall of the opening D in the sleeve 0 are rounded, so as not to present any sharp edges to the thread in its passage through said opening.

toward the spindle, a recess on its upper wall or edge and shoulders rising from said wall at the terminals of said recess, in combination I 5 with a screw which is connected with the body of the shuttle and having its head adapted to overlap said recess and engage either of said shoulders.
